Address Book Application Using Typed Dataset & Bound Controls?
May 29, 2010
I am writing a simple Address Book Application using Typed Dataset & Bound Controls. 1<sup>st</sup> Form for Entering Addresses 2<sup>nd</sup> Form for Adding New 'CITY'. To select a city for address I am using a data bound combo box which shows a list of Cities.
While entering with a address if user found the required City Name is not found in the Combo list, he opens a 2<sup>nd</sup> Form to Add a City name to database & returns to Form1.
Here the expected newly added city doesn't appear in the combo list, so I tried to Refill the underlying table with following code

I don't normally use strongly typed datasets, but I am maintaining an existing application that uses them.This application has a form to edit rows in detail view, so we have the navigator toolstrip with nav buttons on top, including one to add a new row.When this button is clicked, I need to update one of the bound text boxes with a value from the underlyingThe field in question is defined as nvarchar 25 It's almost always integers in this field, but one row has a string.In the dataset, I have a table adapter to go get the max value + 1 where the field is numeric, like this:
SELECT internal_num = CAST(MAX(internal_num) + 1 AS NVARCHAR(25))
FROM dbo.invoice_log
WHERE ISNUMERIC(internal_num) = 1

We are binding most of our text boxes and dropdown boxes to a BINDING NAVIGATOR (with a DATA SOURCE of a DATA TABLE).When the BN is clicked through the text boxes all change immediately.We need to use some non-bound controls as well.First one is 4 radio buttons that when clicked will change a single value in a DATA TABLE.What would be the best method to do this? Should I track when the CURRENTCHANGED event occurs on the BINDING NAVIGATOR.I'm thinking that I could trick this by BINDING the SINGLE FIELD to a HIDDEN TEXTBOX and when that textbox CHANGED event occurs mess with the radio buttons and visa-versa.

The problem is in the line that contains address.save(filename) the part address.save is underlined. When I backspace over the save, it gives me the options of what can go there and save isnt one of them. I am coping this out of a book.[code]...

I have a SQL Server Data Base that I use to keep all my contact information so that I have it in one central location and can easily add more data to it. I want to be able to do two things:
1. Update the Windows Address Book or Outlook Express or Outlook directly from an application on my PC. Add, delete and update contacts and all contact data. Eventually, I would also like to be able to change the options if possible.
2. Update contacts in Blackberry devices directly from a PC application. Again, Add, Delete and Update contacts and all contact data. Currently, I have two Blackberry 9000 Bolds, but eventually I do not want to be limited to only this model, and I will also want to be able to set options on Blackberry devices.
Currently, I update the Windows Address Book with a CSV file created from my Data Base Application and import it using Outlook Express Import. However, Outlook Express will not import or export all fields. For example: Spouse, Birthday, IPAddress, Anniversary and more. I know that these fileds can be updated because the Blackberry Desktop Manager can do it.
It is a pain to have to first Sync Outlook Express with my Data Base and then Sync the Blackberry with Outlook Express. Especially when all fields are not updateable via CSV and the Blackberry Desktop Manager does not map all Outlook Express fields. However, it does map more fields than what are avaliable via CSV which is how I know that it is possible to update more fields in the Windows Address Book.
I use Visual Studio 2005 soon to be 2008 (maybe ) on Windows XP SP 3, 3.0 Ghz intel Pentium IV, and I do know that there is a Blackberry plug-in for VS which I have downloaded but it is not installed (no experience with it nor do I know what it might do to VS).

I want to add an address book to my emailer. I have 2 buttons on my main form,
button1 = Add Contact To Address Book , button2 = Import Email Address.
Basically when I click add I want another form to open and the user to be able to add an email address and save it and if I click import I want the same form as the "Add contact" and enable the user to select a contact and add it to textbox1 on my main form.

I need to make an address book that doesnt use a database.It suppose to have [code]All information shall be stored in a structure at run time.The application should read and write to a data file.Make sure the application includes previous, next, add, save, and delete buttons.When graded by your instructor, there should be at least five entries in the address book.But the book doesnt show me how to do it and the only online stuff I can find is threw databases and nothing else. I asked the teacher and he says no database for this one, the idea is to use flat files (txt) and I have no idea how to even really start this one.[code]

I need to be able to get the current users LAN id using VB.NET and then use this info to pull out the phone number and full name and perhaps other dept info from the address book in outlook. The application I am building is web based in VS 2008, and the users will access the site once they have logged into the companies network. So I need to obtain their LAN ID. They will then be able to send an email using the smtp client. I need the email to send the lan ID of the person as well as include the address book info in the subject. how to use the smtp client.

I have been assigned to create a simple address book in VB 2005 and have got as far as I can with it. Contact entries are to be stored as an array of objects rather than to .txt file or access database (I know they will all be lost when shut down). I suspect this is probably pretty straightforward if you know anything about VB - unlike myself obviously.

Private objContact As New ArrayList
Private Sub BtnAddContact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnAddContact.Click

I've recently decided to switch from VB6 to VB2008 and am looking for some advice for a certain type of book I seek.Already I've aquired several VB2008 books, but the type of reference book I'm seeking I can't find.For VB6 I have a book called "The visual guide to visual basic". It's a very very very very old book but its gold, platinum and diamonds in one.This book basically takes ALL controls, commands, etc, and in alphabetical order as a sort of encyclopedia, explains its purposes, possibilities, properties together with many examples.
If I was uncertain about a control or command I could simply look it up in this book and almost always find what I was looking for.My question, does anybody know of an equivalent for VB2008?

I am experiencing a perplexing error ("Index was outside the bounds of array") that did not surface a few days ago WITH THE CODE UNCHANGED.
I was even able to successfully create an executable file a few days ago. It was therefore a shock to be given this error when testing it today.
The snippet is shown below:

Dim parts() As String = lines(x).Split(",")

I created a dataset in Visual Studio 2010 containing two tables: tblCategories and tblAnswers. tblCategories has two columns: CategoryNumber (AutoNumber and primary key) and CategoryName. tblAnswers has three columns: AnswerNumber (AutoNumber and primary key), Answer, and CategoryNumber. The CategoryNumber columns in each table are related. I have a command button which I want to use to add a record to the CategoryName column in tblCategories with the data typed in a textbox. When I try to access the dataset to add a new row(dataset.tblCategoriesDataTable.NewRow), the NewRow method isn't present. I've done some reading which suggests that I need a TableAdapter, but it seems like that is for connecting to an external file because I have to select a connection. I have no external SQL files or database. I want the user to be able to create a database within my program.

I've got a typed dataset. I bind the data with a binding source to a form with arround 200 textboxes, dataedits and so on. Everything works fine with one exception:In my database I have empty DateTimes (DBNull.Value). And when they get bound to a DateEdit-Control, I get the following exceptions:
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.Data.StrongTypingException' occurred in myTestDLL.dll
I tried to change the NullValue-Property in the DataSet-Desinger to something else as 'Throw Exception', but it doesn't work for a DateTime. For other types like Integer or String it works fine.I dont know a nice solution (right now I fill the empty dates with some dummy date and make it invisible in the DateEdit-Control, but this is very uncool) and I hope to find some help here.

I am looking for a VB.net book that strings me through the entire development process of an application (Prefered: WPF ,LINQ ,ADO). I have read a few books on OOP and VB.net with small code samples demonstrating the specific idea of the chapter.I think it would be really helpful if there was a book that programmed an entire application that uses a sql database (Northwind , Adventureworks).

Firstly here's the code and i will explain my problem underneath. [code...]
Now as you can see I have a variable that holds a value member of the combo box Products which is the productID of the current product selected. Then it searchers through the products datatable and once its found the correct product or not it stores the answer in slectedproductrow. next I test to see if selected product row has found the product if it has i then see if the product has already been added to the order by seraching the the customer current order datatable if it hasn't it adds the current information to the order by using selected product row.
Now the problem i get is when i add the same product it still adds the information again as currentorderrow comes back as nothing everytime even if the product has been added before but if it was in the table which it should be it should skip that bit and just go to add the current qtys toghther.Also if i go to add a diffrent product it overwrites the the other one. So i can't store the customer order. Its like i can't store more than one row. By the way I have a datagrid and can see the product get over wrriten.
